Can complex life on alien planet with dying atmosphere EM field ozone sn2behigh radiation able to adapt so it doesn't breathe and is resistant to the extreme pressure temperature etc in space planet?

Answer 1

Possibly, however the chances are extremely thin by its own methods therefore it seems far more likely that the organism will perish.

Answer 2

It is unlikely that complex life could evolve to adapt to such extreme conditions as described. The combination of a dying atmosphere, high radiation, extreme pressure, temperature variations, and living in space would present numerous challenges that would be difficult for any life form to overcome. Additionally, the need for an alternative to breathing and resistance to such extreme conditions would require significant biological adaptations that may fall outside the realm of possibility.
